Abstract

The invention relates to PID control based self-focusing lens ion exchange temperature control method and system. The method is characterized by adjusting a PD control parameter by using mode recognition in artificial intelligence and inference judgment in an expert system; the expert system sums up artificially adjusted experience and skills into a series of adjusting rule firstly, and then carries out analysis and judgment on controlled system information which is collected in real time, automatically selects an adjusting rule, compares a response curve of a controlled object with a control target curve and carries out repeated adjustment and comparison till a control target is met. The system mainly comprises a thermocouple (1), an adjustment amplifying circuit (2), data collecting cards (3 and 7), a computer (4), a photoelectric isolating circuit (5), and a thyristor power adjusting and temperature controlling circuit (6), wherein the thermocouple (1) is installed in a heat treatment furnace, and the computer (4) is provided with PID control software. The invention has high temperature control precision, can reduce the requirement on the automation level of equipment and is beneficial to reducing the production cost.

Description

technical field

[0001] The present invention relates to a heat treatment temperature control method and device, in particular to a method and device for controlling the ion exchange temperature of glass filaments in the manufacturing process of a self-focusing lens, in particular to a method for controlling the ion-exchange temperature of a self-focusing lens based on PID control and devices. Background technique

[0002] As we all know, the self-focusing lens is a radially variable refractive index lens with small diameter (can be less than 1mm), short focal length (the focus can be located on the end surface), large numerical aperture (can be greater than 0.6), and high imaging resolution (can be greater than 300lp / mm), small exit spot (can be less than 1 micron), good aberration elimination performance, and good collimation, convergence, and beam expansion capabilities for incident light information. It has a wide range of applications in optical fiber communication, sen...
